Keyhole effects in MIMO wireless channels - measurements and theory
(2003) IEEE Global Telecommunications Conference, 2003 p.1781-1785- Abstract
- It has been predicted theoretically that for some environments, the capacity of wireless MIMO systems can become very low, even for uncorrelated signals; this effect has been termed "keyhole" or "pinhole". We present the first unique measurements of this effect. The measurements were performed in a controlled indoor environment that was designed to obtain a keyhole. We analyze the limitations for measurement-based capacity calculations and keyhole investigations. We further present error bounds for the capacity and eigenvalue distributions due to measurement imperfections, such as finite signal-to-noise ratio and multipath leakage. The bounds are compared to the measurement results and show excellent agreement. Finally, we analyze the... (More)
